Introduction To Knowledge of Injection Molding Machine Operation Precautions

Nov. 25, 2020


Before booting


1.Check whether there is water or oil in the control box of the Plastic Injection Molding Machine. If the electrical appliance is damp, do not turn it on. Maintenance personnel should dry the electrical parts before turning it on


2. Check whether the power supply voltage meets, generally should not exceed ±6%


3. Check whether the emergency stop switch and the front and rear safety door switches are normal. Verify that the rotation direction of the motor and the oil pump are the same


4. Check whether the cooling pipelines are unblocked for long distances, and pass cooling water to the oil cooler and the cooling water jacket at the end of the barrel


5. Check whether there is lubricating oil in each movable part, and add enough lubricating oil


6. Turn on the electric heating to heat each section of the barrel. When the temperature of each section reaches the requirements, keep it warm for a period of time to stabilize the temperature of the Automatic Injection Molding Machine. The heat preservation time varies according to the requirements of different equipment and plastic materials


7. Add enough plastic in the hopper. According to the requirements of different plastic injection molding, some raw materials are best to be dried first


8. It is necessary to cover the heat shield on the barrel, which can save energy and extend the life of the electric heating coil and current contactor

During operation of the injection molding machine


1.Do not cancel the role of the safety door at will for convenience


2. Pay attention to the temperature of the pressure oil, and the oil temperature should not exceed the specified range. The ideal working temperature of hydraulic oil should be kept between 45-50℃, generally within the range of 35-60℃, it is more appropriate


3. Pay attention to adjust each travel switch to avoid impact when the machine moves


At the end of the injection molding machine


1.Before stopping the machine, the plastic in the barrel of the Injection Molding Machine should be cleaned to prevent oxidation of the leftover material or long-term thermal decomposition


2. The mold should be opened to make the toggle mechanism time locked


3. The workshop must be equipped with lifting equipment. Be very careful when assembling and disassembling molds to ensure production safety
